Abstract

To allow flexible security level switching according communication situations, a password holding section holds a plurality of device authentication passwords, for example, a temporary password and a private password. The temporary password is valid only under a certain situation and the private password has a high level of confidentiality to increase the device security. A password management section allows the user to add a new password to the password holding section and delete an existing password therefrom. A password selecting section selects the most suitable password for current connection from among passwords in the password holding section according to a user event, information acquired by an external factor acquisition section, and information from a time control section. The selected password is output to a password checking section.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2000-131861, filed Apr. 28, 2000, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to a radio communication device and a user authentication method using user authentication passwords.[0003]In recent years, attention has been paid to radio communication systems adapted for personal areas, such IrDA, Bluetooth, HomeRF, etc. Particularly, Bluetooth and HomeRF have merits of no directivity and high transparence over infrared communication systems, such as IrDA, and are greatly expected to develop and find wide application in the future. The Bluetooth is short-haul radio communication standards and establishes radio communications within 10 m or 100 m using the ISM (Industrial Science Medical) band of 2.4 GHz band. The Bluetooth adopts frequency-hopping...
